As is well known, B0 d,s–B̄0 d,s mixing offers a profound probe into the effects of physics beyond the standard model. The data obtained at the e+e- B factories have already provided valuable insights into the Bd-meson system, and very recently also...

We present a systematic study of twist-3 and twist-4 light-cone distribution amplitudes of the K meson in QCD. The structure of SU(3)-breaking corrections is studied in detail. Non-perturbative input parameters are estimated from QCD sum rules and re... Read More about Higher-twist distribution amplitudes of the K meson in QCD.

We present an improved calculation of B--> light vector form factors from light-cone sum rules, including one-loop radiative corrections to twist-2 and twist-3 contributions, and leading order twist-4 corrections. The total theoretical uncertainty of... Read More about Bd,s→ρ,ω,K*,ϕ decay form factors from light-cone sum rules reexamined.

We present a new calculation of the Brightarrowpi form-factor f+, relevant for the measurement of |Vub| from semileptonic Brightarrowpi transitions, from QCD sum rules on the light-cone. The new element is the calculation of radiative corrections to... Read More about Improved analysis of B → πeν from QCD sum rules on the light-cone.
